swift - 为什么我的图像没有全屏显示？

Question

我遇到以下问题。我在 View Controller 中有大约 10 个不同的图像。现在我希望图像在点击时切换到全屏。我已经将允许用户交互选项设置为"is"，并输入我在该网站上找到的以下代码:

import UIKit

class ImageViewController: UIViewController {


    @IBAction func imageTapped(sender: UITapGestureRecognizer) {
        let imageView = sender.view as! UIImageView
        let newImageView = UIImageView(image: imageView.image)
        newImageView.frame = self.view.frame
        newImageView.backgroundColor = .blackColor()
        newImageView.contentMode = .ScaleAspectFit
        newImageView.userInteractionEnabled = true
        let tap = UITapGestureRecognizer(target: self, action: "dismissFullscreenImage:")
        newImageView.addGestureRecognizer(tap)
        self.view.addSubview(newImageView)
    }

    func dismissFullscreenImage(sender: UITapGestureRecognizer) {
        sender.view?.removeFromSuperview()
    }

有谁知道为什么我的图像无法点击并变成全屏？

确保 ImageView 的 userInteractionEnabled = YES 并且这是您在这里尝试执行的操作的示例 https://github.com/abhinavsingh77/ImagePreview
